BRAKE PAD THICKNESS

1 1
WARNING WARNING
Always replace brake pads in complete sets for correct
brake operation. Never replace just one brake pad. Fail-
ure to install brake pads as a set could result in death or
serious injury.
Check brake pads for minimum thickness:
At the 1000 mile (1600 km) service interval.
At every 2500 miles (4000 km) service interval thereafter.
At every scheduled service interval thereafter.
Check front brake pad:
At the 10000 mi (16,000 km) interval or as required.
Check rear brake pad:
At the 25,000 mi (40,000 km) interval or as required.
See Figure 1-11. Inspect brake pads for damage or excessive
wear. Replace both pads as a set if friction material of either
pad is worn to 0.040 in. (1.0 mm) or less. If this amount of
wear occurs, wear grooves will disappear from friction mate-
rial surface.

BRAKE ROTOR THICKNESS

1 1
WARNING WARNING
Do not allow brake fluid, bearing grease, lubricants, etc.
to contact brake rotor when servicing motorcycle or
reduced braking ability will occur, which could result in
death or serious injury.
Check brake rotors for minimum thickness:
At the 1000 mile (1600 km) service interval.
At every 2500 miles (4000 km) service interval thereafter.
At every scheduled service interval thereafter.
1. Measure rotor thickness. Replace rotor if minimum thick-
ness is less than 0.18 in. (4.5 mm). Replace drive bush-
ings, fasteners, washers and springs whenever rotor is
replaced.
2. Check rotor surface. Replace if warped or badly scored.
